Abstract: Series of measurements with single and multiple automated injection of a constant volume of 50 $\mu$l into the HGA 72 applying solutions with ppb amounts of Cu, Cd, and Pb and calibration curves had been performed. Further precision of automated injection is determined and compared with injection by hand using an Eppendorf pipette. After that the influence of HCl, HNO$_{3}$, and HCl0$_{4}$ at relatively low and elevated acid concentrations on signal height and reproducibility for 2,5 ng Pb, memory effects for Pb, and Cd, and life time of graphite tubes with Cd and Pb had been studied. Advantages and disadvantages of the examined prototype systemrefering to routine and scientific applications are discussed.
